D6055 — Implant connecting bar (for overdenture)
D6055 is the bar screwed across several implants that an overdenture then clips onto.
This code belongs to a set of five covering implant abutment and surgical guide. The clinical detail lives in the implant abutment and surgical guide guide; the code-level detail is here.
What follows: the specifics built into the number, the money, the benefit treatment, and the line separating it from the codes it is easiest to confuse it with.
D6055 against the codes beside it
D6056 — Prefabricated implant abutment: It is a stock, off-the-shelf abutment: the connector screwed into the implant that the crown then sits on.
D6057 — Custom implant abutment: It is an abutment machined or cast for one implant individually, used where a stock component will not suit the angle or the gum contour.
D6051 — Interim implant abutment placement: It is the interim version.
D6190 — Radiographic/surgical implant index (guide): It is the radiographic or surgical guide made before implant surgery, the template that positions the drill.
Those four codes and D6055 are the whole group — nothing else describes this procedure. The safest question to ask is not "what does this cost" but "which code is going on the claim". The first answer changes; the second decides the first.
